What is the easiest way to deal with the hollow drum of kitchen and bathroom tiles

The reason for the hollowing is that the waterproof layer is not made or the tile adhesive is not up to standard. The hollow drum part is knocked off directly, and a layer of interface agent is used after the solid part of the base surface is treated, and the top is directly tiled or other steps are done. Master Jin's interface agent is not bad, and the permeability and adhesion are relatively good.

Or wrap it up for someone else to make.

It doesn't have to be replaced. First, check the floor tiles in the entire store or room to see if the individual tiles are hollow or large arches. When inspecting, you can use to tap the tile, if the sound is empty, it is already hollow, that is, the tile has been separated from the cement layer.

Such tiles can easily crack if they are barely pressed down. Therefore, it is necessary to pry up the arched tiles, re-pavement, and if there are a large number of hollow tiles, they should simply be re-paved in their entirety. First, the joint between the arched tile and other tiles is sawed with a cutting machine (there will be a lot of dust when cutting, so you need to keep adding water to the cutting machine), you should be very careful to lift the tile, the action must be light, otherwise it is easy to cause the tile to crack.

2. Scrape off all the cement mortar that sticks to the edge of the tile. Treat the cement layer under the bricks, plane off 1-2 cm and clean it up. 3. Evenly coat a layer of mixed cement mortar.

The ratio of cement yellow sand is: wall tiles 1:3, floor tiles:

1:2-3, the cement number of cement is No. cement. In addition, if white cement is used, be sure to use 108 glue, which can make the cement and floor tiles tightly bonded.

Fourth, the cleaned tiles are re-paved, flattened, and then reinforced with a caulking machine after the cement is completely dry, so as to avoid the phenomenon of upturned and cracking of the floor tiles.
